The S4RS is a 2007 with 696 miles. It has about $8,000 in aftermarket, including a full Termignoni exhaust system (new ecu as well programmed for the exhaust) slipper clutch, quick change sprockets, and a ton of carbon fiber bits. They don't make a liquid cooled monster anymore (it was replaced by the new street fighter) so finding clean S4R's is going to be tough. One owner bike

$13,000

The S2R800 is a very rare color of Black and "tangerine." Interestingly they made a reverse of the color scheme that same year, "tangerine" with a black stripe. This Monster only has a few modifications including aftermarket mirrors, carbon fiber front fender, and the very popular "tail chop" fender eliminator modification. Under 6,000 miles on this one. One owner bike.

$6,200

Both bikes are located in NH. Please send me a PM on here or give me a call: 603-524-4898

UPDATE:
Another S2R1000 for sale...this one is SUPER clean. It is an 08 with only 154 miles! Nearly completely stock. The owner of this bike hurt his back, and has undergone several surgeries, and can no longer ride.
